Benefits of technology

[0006]An object of this invention is therefore to overcome this drawback by providing a legged mobile robot control system that is improved in communication capability by enabling it to shake hands with humans and can maintain a stable posture during the handshaking.

Problems solved by technology

When a robot is controlled to shake hands with a person, its arm receives a considerable external force.
However, the external force applied by handshaking may well be strong enough to disturb the posture of a legged mobile robot, particularly a biped robot, that moves by driving legs.
In other words, the posture of the legged mobile robot is liable to be destabilized by the action of shaking hands with a human.

Embodiment Construction

[0018]A legged mobile robot control system according to an embodiment of this invention will be explained with reference to the attached drawings in the following.

[0019]FIG. 1 is a front view of a robot, specifically a legged mobile robot, for which the control system according to an embodiment of this invention is applied and FIG. 2 is a side view of the robot shown in FIG. 1. A biped humanoid robot having two legs and two arms is taken here as an example of a legged mobile robot.

[0020]As shown in FIG. 1, a legged mobile robot (hereinafter called simply “robot”) 10 is equipped with right and left legs 12R, 12L (R and L indicating the right and left sides; hereinafter the same) that are connected to the lower portion of a body 14. A head 16 is connected to the body 14 at its upper portion and right and left arms 20R, 20L are connected one to either side of the body 14. Hands (end effectors) 22R, 22L are attached to the distal ends of the arms 20R, 20L. A housing unit 24 is mounted o...

Abstract

In a legged mobile robot control system having leg actuators each driving the individual legs and arm actuators each driving the individual arms, an external force acting on the right arm is detected, operation of the right arm actuators is controlled to produces a handshake posture, and operation of the leg actuators is controlled based on the detected external force acting on the right hand during handshaking, thereby improving communication capability by enabling it to shake hands with humans and to maintain a stable posture during the handshaking.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a legged mobile robot control system, particularly to a system for controlling a legged mobile robot that is equipped with legs and arms attached to a body to be able to move by driving the legs, and to operate the arm to shake hands with a person.[0003]2. Description of the Related Art[0004]The prior art includes robots made capable of shaking hands with people so as to upgrade their ability to communicate with human beings, as taught by, for example, Japanese Laid-Open Patent Application No. 2004-283975, particularly paragraphs 0062 to 0066 and FIGS. 8 and 9. The robot taught by this reference has a pressure sensor embedded in its hand. During handshaking with a person, the person's gripping force is detected to make different utterances depending on the intensity of the detected gripping force. (It says “How do you do?” when the force is about right and “Ouch” when it is too strong.) It is a...
